Just divide the output force by the input force.Just divide the output force by the input force.Just divide the output force by the input force.Just divide the output force by the input force.
Input and output are shown on a force diagram by the human being the input force and the load force being the output force. When you divide output force by input force, you get the mechanical advantage of a lever.
No. A light bulb can only USE energy, it cannot STORE it. Before it can operate it needs to be given a supply of electrical energy and, from that input of energy, it produces outputs of energy in the form of heat and light.
The input force is how much force you use to pull on it. The output is what is lifted.
Input to light bulb is Electricity and output is light.
Because efficiency is measured in Output/input. At the same light bulb output, one with lesser energy input required is higher in efficiency. Possible confusion come from description of low energy light bulb without stated the high or low energy is compared at what lux it can produce light.
Assuming that a sensor (any type, heat, light, sound etc) is connected to something - eg a computer or a switch etc. it is an 'input' device. The device which created whatever is being 'sensed' is an output device. For example if you put a thermometer next to a light bulb to see how hot it is then the bulb is 'output' and the thermometer is 'input'.
Light Pen is an input Device.
input can only receive while output can only send. For example a light bulb can only receive electricity whilst a socket in the wall can only send electricity.

Light Pen is an input Device.
Input is electricity and output is sound, heat and light.

Light bulb in the home - alternating current (A/C) Light bulb in a car - direct current (D/C) Output of a battery charger - direct current Input of a battery charger - usually alternating current
Both bulbs output the same amount of energy. The difference is in how much of that energy is output as heat vs the energy output as light. In a standard incandescent light bulb about 10% of the energy is output as light while the other 90% is output as heat. This makes the bulb only 10% efficient. For a florescent bulb the output of light is about 50% and the other 50% is output in heat. This means that a fluorescent bulb outputs five times as much light for the same wattage as a standard incandescent bulb, hence you can get the equivalent of 100 watts of light output for only 20 watts of electricity.
